First Defense
A downloadable game
The FIRST DEFENSE simulation wargame is designed to exercise United States Space Corps officers and enlisted men in the control and coordination of ground, Lunar, and spaceborn assets across multiple operational theaters, with varying levels of international cooperation, and against multiple threat profiles.
Direct from a moonbase in the near-future of a 1992 that didn't happen comes the instructional wargame First Defense, a singleplayer map-and-chit game with (somewhat) realistic orbital mechanics and space combat. Learn the same way that the 3rd Lunar Bombardment Division does, and prepare yourself to serve in the defense of Earth against aliens that are entirely hypothetical.
Contains a rulebook with 9 combinations of scenarios, a map, 126 printable chits, and an extra one-page map for display, or fun. Does not come with a six or ten-sided die, which are required for play.

Could it be possible to make an annex with vocabulary for all the acronyms ? I have trouble naming all the orbits
I don't have any plans to add an annex - but the orbits are generally decoded as such:
L---: Low
M---: Medium
G---: Geosynchronous
H---: High
-T--: Tropical (0-30 degrees inclination on Earth)
-I--: Inclined (30-60 degrees inclination on Earth, 45-90 degrees around the Moon)
-E--: Exotic/Eccentric (mostly represents Tundra and Molniya orbits)
-P--: Polar (60-90+ degrees inclination on Earth)
--E-: Earth
--L-: Lunar
So, LTEO is Low Tropical Earth Orbit, for example. The only exception is LTO, being Lunar Transfer Orbit. Hope that helps!
Thanks a lot !
